Influence of self-organized fluid flows on structure and network formation in self-supporting layers made of hyaluronan

Popis výsledku v původním jazyce

The spatial arrangement of bio-macromolecular systems affects their function and physiological role. This study presents a new approach to induce changes in the secondary and tertiary structure of macromolecules without altering pH or ionic strength. By utilizing self-organized fluid flows, known as Bénard-Marangoni convective instability, we observed alterations in mean coil size, thermal stability, and self-organizing capabilities of hyaluronic acid. These changes manifested through modified surface activity and the formation of self-supporting polymeric film. Additionally, we investigated the factors influencing network formation and aggregation of hyaluronan on mica surfaces. Temperature-induced self-organization in fluid state as well as molecular weight or concentration influenced the macromolecular arrangement such as aggregate size or fibrillar network density at the liquid-solid interface. The understanding of hyaluronan&apos;s conformational variability is of great importance as it governs its processability, and formulations in coatings and self-supporting layers with improved mechanical properties.
